In 2026, B2B buyers are rewarding suppliers with real-time data, flexible payment terms, and self-service buying — and abandoning suppliers that force them into manual, rep-gated, or rigid-payment workflows. Five shifts are driving that split most clearly, and each one has a measurable winning behavior and a measurable losing one behind it.
Key takeaways
- 29% of B2B buyers have walked away from an online purchase specifically because flexible payment options weren't available at checkout (Credit Key, 2026 B2B Buyer Insights).
- 73% of B2B buyers are now willing to place orders over $50,000 through self-service digital channels — no rep required (McKinsey B2B Pulse).
- Gartner expects AI agents to intermediate 90% of B2B buying by 2028, which means supplier data and payment terms increasingly need to be machine-readable, not just human-readable (Gartner, 2025).
1. Winning: real-time, accurate data. Losing: static catalogs and guesswork.
B2B buyers have zero tolerance left for inventory, pricing, or shipping data that doesn't match reality. When a supplier's site shows the wrong stock level or a delivery estimate that turns out to be wrong, buyers don't just get annoyed — they leave. A majority of B2B buyers say inaccurate online data has pushed them to consider switching suppliers, and order errors remain common enough that they actively discourage buyers from using online ordering at all (Sana Commerce, 2025 B2B Buyer Report).
What's changed for 2026 is the bar buyers use to judge "accurate." It's no longer "close enough" — it's live, ERP-synced data that matches what the supplier's own sales team sees internally. Suppliers still running static product catalogs or batch-updated pricing are increasingly treated as a liability, not a convenience.
2. Winning: payment flexibility at checkout. Losing: negotiated terms after the fact.
This is the shift with the clearest revenue math behind it. Nearly 30% of B2B buyers have abandoned a purchase because flexible payment options weren't available at checkout, and 82% of buyers say payment flexibility is an important factor when choosing a supplier in the first place (Credit Key, 2026 B2B Buyer Insights). The same research links offering flexible terms to a 40% increase in conversion rates and a 60% average increase in order size.
The underlying cause isn't financial distress — it's cash flow management. Buyers increasingly expect net terms, purchase orders, and instant credit to be available at the point of purchase, not negotiated by phone afterward. Suppliers still routing every credit conversation through a manual approval process are handing that order — and the buyer relationship — to a competitor who doesn't.
3. Winning: self-service for high-value orders. Losing: forcing buyers through a rep.
The idea that self-service is only for small, low-stakes purchases is now out of date. 73% of B2B buyers say they're willing to place orders over $50,000 through digital, self-service channels, and McKinsey's research shows buyers now split their time roughly evenly across in-person, remote, and digital self-serve interactions — the "rule of thirds" that holds regardless of deal size (McKinsey).
Suppliers that still gate large or complex orders behind a mandatory sales call are increasingly working against buyer preference rather than serving it. That doesn't mean human reps disappear — it means they need to be an option for complexity, not a requirement for scale.
4. Winning: machine-readable data and terms. Losing: information only a human can parse.
This is the shift that's genuinely new for 2026, and it barely existed in last year's B2B ecommerce conversation. Gartner predicts that by 2028, 90% of B2B buying will be intermediated by AI agents, moving more than $15 trillion in spend through automated, machine-to-machine transactions (Gartner, 2025). Industry analysts covering the shift note that AI purchasing agents evaluate suppliers on how cleanly their pricing, financing terms, and fulfillment data can be parsed programmatically — and will route demand elsewhere before a human on the supplier's side even knows the opportunity existed (PYMNTS Intelligence, February 2026).
In practice, that means product specs, pricing logic, and payment terms need to be exposed in structured, API-accessible formats, not buried in PDFs or a sales rep's head. Suppliers treating this as a future problem are already behind the buyers — and increasingly the software — evaluating them today.
5. Winning: verifiable sustainability data. Losing: unverifiable claims or silence.
Sustainability has moved from a marketing checkbox to a hard purchasing filter. In Bain & Company's 2025 global survey of 750 B2B companies, 49% said they're already buying more from sustainable suppliers, up from 39% the year before, and 68% plan to increase that further over the next three years. More strikingly, 26% of B2B buyers are actively dropping suppliers that don't meet their sustainability criteria today, a figure Bain expects to nearly double to 49% by 2028 (Bain & Company, via ESG Today, 2025).
The losing move here isn't a lack of sustainability effort — it's a lack of verifiable, accessible proof of it. Buyers increasingly rank "sustainability of the offer" second only to quality in purchasing criteria, and suppliers who can't produce that data quickly are being filtered out before price even enters the conversation.
The common thread
Four of these five shifts trace back to the same root cause: buyers (and increasingly their software) reward suppliers who can make decisions instantly and penalize those who make them wait. Real-time data, instant credit, self-service, and machine-readable terms are really one capability wearing different names — the ability to give a buyer a definitive answer the moment they ask for it, instead of routing them through a queue. Sustainability is the outlier, but even there, buyers are filtering out suppliers who can't produce proof on demand. Speed of decision, not just speed of shipping, is what's separating this year's winners from its losers.
Where Two fits in
Two of these five shifts — payment flexibility and machine-readable, agent-ready commerce — sit squarely in what Two was built to solve. Two's Risk-as-a-Service engines make real-time credit and fraud decisions at checkout, so flexible payment terms are available instantly rather than negotiated after the sale, and that same instant, API-accessible decisioning is exactly the kind of structured data an AI purchasing agent needs to transact with a supplier instead of skipping past it. As B2B buying keeps splitting between winners and losers on these fronts, the suppliers who make credit and payment decisions instant and machine-readable are the ones positioned to keep winning the order.
FAQs
What's the single biggest reason B2B buyers abandon an online purchase in 2026?
Payment inflexibility ranks among the top reasons: close to 30% of B2B buyers report abandoning a purchase specifically because flexible payment options weren't available at checkout (Credit Key, 2026).
Are large B2B orders really moving to self-service?
Yes. 73% of B2B buyers say they're willing to place orders over $50,000 through self-service digital channels, and self-service now drives a significant share of B2B revenue for companies that offer it (McKinsey).
Why does "machine-readable" data matter for a human buyer's purchasing decision?
Because increasingly, the decision-maker isn't only human. Gartner projects AI agents will intermediate 90% of B2B buying by 2028, which means the same data quality that helps a human buyer also determines whether an AI agent can complete a transaction with you at all (Gartner, 2025).
Is sustainability actually affecting supplier selection, or is it just talk?
It's measurable: 26% of B2B buyers report actively dropping suppliers that don't meet sustainability criteria today, expected to nearly double by 2028 (Bain & Company, 2025).
